study shows how protein is used in depression

This is really interesting. The study autopisied suicide patients, and has some very interesting findings. The results and DNA tests are not ready to market yet but I think they're onto something here.
(As an aside, I think it's very big-hearted of the families to allow their loved ones to be used in this study, to help other people, and perhaps put their own minds at ease. Very cool. It makes you feel like you're really doing something, in such a helpless situation, you know?)
